November 6, 2026Some of the Finest Known Examples Spent Centuries Underwater or Buried in Bank Vaults
Some of the finest known examples of certain coins spent centuries underwater or buried in bank vaults. I love that story. But let’s look at the hoard history behind this one.
When a collector posts a new addition and the thread is titled “Newest Capped Bust Half Dollar added to my set,” most people expect a date, a variety, and a grade. I see something far more interesting. As a treasure salvor, I see a coin that looks like it survived a hoard — just not the hoards most people first think of. It is a crusty, original, beautifully toned 1820 Capped Bust Half Dollar, ex Chuck Link and Hoosier collections, purchased from dealer Dave Kahn. He described it as having “real flash under the thick, golden-gray dirt patina, with full, flowing cartwheel and luster over every surface.”
That description alone tells me a great deal. I have examined hundreds of Capped Bust halves in the field, on recovery boats, and in bank vaults. I can tell you this: thick, golden-gray dirt patina with flash underneath is not what saltwater gives you. It is not what a shipwreck gives you. It is what decades — sometimes a century — of undisturbed storage gives you. A private collection. A safe deposit box. A buried hoard. The owner, Tom, is now down to just the 1815 and 1821 to close out his date set. He worked his way back to a full set after selling and trading at the ANA. That is no small feat. The 1820s are notoriously difficult in high grade.
So was this coin found in a famous hoard? Was it a sea salvage coin? Was it part of the Redfield Hoard or the Saddle Ridge Hoard? To answer that, we need to understand three things. What shipwreck effects actually do to silver. What the great American hoards actually contained. And how to read the surface of a coin the way I read a wreck site. Let’s take a closer look.
The Coin in Question: An 1820 Capped Bust Half Dollar
In my experience grading Capped Bust Half Dollars, the 1820 humbles even advanced collectors. The series ran from 1807 to 1839. John Reich designed it. It was struck at Philadelphia without a mintmark, in 90% silver and 10% copper, weighing approximately 13.5 grams and measuring 32.5 mm. The 1820 was struck in large numbers. But surviving examples in mint condition or near-mint condition are scarce. Most were heavily circulated in the 1820s and 1830s. And the dies were often weak.
The forum coin is identified by the dealer as an Overton 103. For collectors, that matters. Overton numbers are the standard VAM attribution for Capped Bust halves. This rare variety is known for a full strike when the dies are fresh. The dealer specifically noted, “the strike is as full as the 103 comes.” That is a key authentication and grading marker. On a Capped Bust half, I always check these points first:
- The Liberty Cap: The fold of the cap over Liberty’s head should be defined, not mushy. On the 1820, a weak strike will flatten the cap’s edge.
- The Stars on the Obverse: Seven stars to the left of Liberty, six to the right. The centers of the stars should be sharp. Wear and weak strikes both kill the star centers first.
- Liberty’s Hair Curls: The curls at the base of the neck and behind the ear are a prime diagnostic for both strike and wear. Original, uncirculated examples show separated, individual curls.
- The Eagle’s Feathers on the Reverse: The wing feathers and breast feathers should be fully separated. This is where Redfield and other hoard coins often shine, and where circulated 1820s issues usually fail.
- The Lettering: LIBERTY on the obverse and UNITED STATES OF AMERICA on the reverse should be fully formed, with no flattening on the high points of the letters.
According to Dave Kahn’s description, which Tom trusted enough to buy immediately after watching the video, this coin shows none of the expected wear. “To be perfectly honest, I don’t think the coin ever circulated, and I don’t see anything that could realistically be called wear. The surfaces are lovely, the strike is as full as the 103 comes, and the eye appeal is mesmerizing.” Forum members agreed. They called it stunning, stunningly original, beautifully toned, crusty in the best way. Several suggested it deserved a plus grade.
That crust is important. A thick, golden-gray dirt patina that still allows cartwheel luster to flow underneath is the hallmark of a coin that rested undisturbed for a very long time. It is not cleaned. It is not dipped. It is original skin. As a salvor, I have learned to respect that skin. Once you strip it, you lose the story. And you lose numismatic value.
What Shipwreck Effects Really Do to Silver Coins
I spend my life around sea salvage coins, and I need to be blunt with collectors: the ocean is not a vault. It is a chemical factory. When a silver coin goes down with a ship, especially in deep, cold water like the Atlantic off South Carolina, it does not come up looking like this 1820.
Shipwreck effects on silver are distinct. Once you learn them, they are unmistakable:
1. Concretion and Encrustation
Saltwater, sand, and marine organisms build a hard, rocky concretion over a coin. When salvors recover coins from the S.S. Central America site, many arrive as lumps. After careful conservation, the surface underneath is often pitted, granular, and matte. It does not have flowing cartwheel luster. It has a dull, sandy texture.
2. Pitting and Surface Corrosion
Chlorides in seawater attack silver. Over 150 years underwater, even in cold water, you get deep pitting, especially on the high points. The fields look eaten. On a Capped Bust half, that would destroy the delicate hair curls and star centers completely.
3. Unnatural Toning Colors
Sea salvage coins often show dark gray, black, brown, or iridescent toning that is uneven and blotchy. It is not the even, golden-gray dirt patina described here. Shipwreck toning is aggressive. It penetrates the metal.
4. Weight Loss and Edge Damage
Coins tumbling in sand and surf lose weight and suffer edge knocks. Even coins that settled in soft silt on a wreck site can suffer from sulfide damage from decaying organic material.
This 1820 shows the opposite profile: full flash, full cartwheel, lovely surfaces, no wear. That is not a shipwreck coin. That is a vault coin. A cabinet coin. A hoard coin that never saw the sea. And that distinction is critical for value. Sea salvage coins have a story, but collectors pay a premium for original, uncirculated, crusty Capped Bust halves. So few survived without circulation, let alone without the ocean. That scarcity drives collectibility.
The S.S. Central America: America’s Most Famous Ship of Gold
No discussion of shipwreck effects is complete without the S.S. Central America. She sank on September 12, 1857, in a hurricane off the coast of South Carolina. She carried an estimated 30,000 coins and over $2 million in gold shipments from California miners heading east. She is known as the “Ship of Gold” for good reason.
When treasure salvor Tommy Thompson and his team located the wreck in the 1980s and began recovery in 1988, they brought up a numismatic time capsule. The vast majority of the coins were United States gold: $20 Double Eagles, $10 Eagles, $5 Half Eagles, and $1 Gold Dollars, mostly dated 1857 and earlier. There were also some silver coins. But gold dominates the narrative. Gold does not corrode in seawater the way silver does.
That is a key lesson for collectors. Gold survives the ocean relatively well. Silver does not. A Capped Bust Half Dollar from 1820 would have been 37 years old at the time of the sinking. It could theoretically have been aboard as a circulating coin. But it would not have come up with the pristine, luster-filled surfaces we see on Central America gold. It would have come up pitted and encrusted.
I have handled Central America silver coins in conservation labs. Even the best-preserved examples show a granularity under magnification that you never see on a Redfield or cabinet coin. The fields are not smooth. The luster is gone. It is replaced by a matte, slightly rough texture. The 1820 in this thread has “full, flowing cartwheel and luster over every surface.” That cartwheel is a product of original mint flow lines reflecting light. Saltwater destroys flow lines. Period.
So, could this coin be a Central America coin? In my professional opinion, no. The provenance given — ex Chuck Link and Hoosier collections — points to a long-held private cabinet, not a shipwreck. The surfaces point the same way. The Central America is a wonderful story. But it is not this coin’s story.
The Redfield Hoard: 350,000 Morgan Dollars in a Nevada Vault
If the Central America represents the sea, the Redfield Hoard represents the vault. LaVere Redfield was a Nevada eccentric and investor. In the 1960s and 1970s, he purchased hundreds of thousands of Morgan silver dollars directly from the U.S. Treasury in their original government bags. He stored them in a vault in Reno, Nevada, and in a safe deposit box in Las Vegas. When he died in 1974, his hoard was discovered to contain approximately 350,000 Morgan dollars, plus other coins.
The Redfield Hoard was released to the market in the mid-1970s through dealers like Abe Kosoff, and later through other sales. It is famous for producing an enormous number of gem uncirculated Morgan dollars, many grading MS-65 to MS-67 today. Because Redfield bought coins that had been stored by the Treasury since the 1890s and early 1900s, many had never circulated. They had developed original toning in the bags.
Here is where collectors often get confused. They hear “hoard” and assume any crusty, original coin must be Redfield. But the Redfield Hoard was overwhelmingly Morgan dollars dated from the 1870s to 1904, with a heavy concentration in the 1880s. It did not contain Capped Bust Half Dollars from 1820. Redfield was not buying early American silver in bags from the Treasury. He was buying the last generation of large silver dollars.
What Redfield does teach us, however, is how hoard storage affects a coin’s surface. Coins stored in canvas bags for 70 years develop a characteristic look: soft, even toning, often gray, blue, or gold, with luster preserved underneath. They are not cleaned. They are not dipped. They have that “dirt patina” that collectors love. The 1820 in this thread has that same philosophy of preservation — undisturbed, original, with flash underneath. But it comes from an earlier generation of collectors, the Link and Hoosier cabinets, not from Redfield’s vault.
In my experience grading, I see Redfield Morgan dollars every month. They have a different strike, a different design, and a different toning pattern. A Capped Bust half is a different animal entirely. To attribute an 1820 to Redfield would be like attributing a Model T to a 1960s car hoard. The dates simply do not align.
The Saddle Ridge Hoard: The Kyd Hoard and a Nevada Time Capsule
The Saddle Ridge Hoard is the most recent great American hoard discovery. It captures the imagination of treasure hunters. In 2012, a couple walking their dog on a trail in the Saddle Ridge area of Nevada discovered a rusted canister containing 1,427 gold and silver coins, valued at over $10 million. The hoard became known as the Kyd Hoard after the couple’s last name.
The Saddle Ridge Hoard contained a stunning mix of 19th-century United States coins. That included 1870-S Seated Liberty Dollars, 1873-CC Seated Liberty Dollars, 1870-S Double Eagles, 1885-CC Morgan Dollars, and many other key dates. The coins ranged from the 1850s to the 1890s. They appeared to have been buried in the late 1800s, possibly by a bank or an individual during a period of unrest.
What made Saddle Ridge so important numismatically was the condition. Many coins were uncirculated, with original surfaces, because they had been buried and forgotten. They had not been cleaned by later generations. They had that thick, original patina that collectors crave.
Could the 1820 Capped Bust half be from Saddle Ridge? Again, the dates make it highly unlikely. The Saddle Ridge Hoard’s earliest coins were from the mid-19th century, not the 1820s. The hoard was buried decades after the 1820 was minted. While it is theoretically possible that an older coin was included, the published inventories show no Capped Bust halves. More importantly, Saddle Ridge coins were buried in soil in Nevada. That produces a different toning environment than a cabinet in Indiana or a collection in the Midwest.
I have examined Saddle Ridge coins at auction. They often show a deep, earthy toning, sometimes with hints of blue and purple from the soil, and a slightly rough texture from the burial. The forum coin is described as golden-gray dirt patina with flash and cartwheel. That is more consistent with long-term cabinet storage in a dry environment. Perhaps in an envelope or a coin cabinet. Not with burial in Nevada soil.
The lesson from Saddle Ridge for collectors is powerful: originality is king. The market paid enormous premiums for Saddle Ridge coins not just because they were rare dates, but because they were untouched. That same premium applies to this 1820. Its value is not because it is from a famous hoard. It is because it survived as if it were from one — original, undisturbed, and uncirculated.
How to Tell a Hoard Coin from a Shipwreck Coin from a Cabinet Coin
As a salvor, I am asked this question constantly: How do you know where a coin has been? The answer is in the surface. Let me give you a practical guide I use when I examine a coin in hand:
- Look for Cartwheel Luster: Tilt the coin under a light. Original, uncirculated coins from a vault or cabinet will show cartwheel luster rotating as you tilt. Shipwreck silver will not. The luster is destroyed by saltwater.
- Examine the Fields Under Magnification: Hoard and cabinet coins have smooth fields with original mint texture. Shipwreck coins have a granular, sandy texture, even after conservation.
- Check the Color Uniformity: Cabinet dirt patina is often even, golden-gray, or light brown. Burial toning can be darker and more mottled. Shipwreck toning is blotchy, dark, and often accompanied by pitting.
- Assess the Edges: Shipwreck coins often have a rough, corroded edge. Hoard coins stored in bags have soft, even edges. Cabinet coins have sharp, original edges.
- Look for Conservation Scars: Sea salvage coins have almost always been conserved. You will see evidence of cleaning, dipping, or stabilization that a true cabinet coin will not have.
By these standards, the 1820 in the thread is a classic cabinet coin with hoard-like preservation. It has the flash, the cartwheel, the original dirt patina, and the full strike. It does not have the scars of the sea. It does not have the soil toning of Saddle Ridge. It does not have the bag toning of Redfield Morgans. It has its own story: struck in Philadelphia in 1820, saved from circulation, placed in a collection, passed from Chuck Link to the Hoosier collection, and now to Tom.
Why the 1820s Are So Difficult — And Why This Coin Matters
Collectors often ask me why a common date like the 1820 Capped Bust half is so expensive in high grade. The answer is survival. Most 1820s were spent. They were workhorse coins in the 1820s and 1830s, before the Seated Liberty design replaced them in 1839. They circulated heavily. They were melted. They were damaged.
Finding an 1820 Overton 103 with no wear, full strike, and original surfaces is like finding a shipwreck coin in perfect condition. It defies the odds. The forum members recognized this. They noted that “20’s aren’t easy, that’s for sure.” Tom was down to the 1815 and 1821 to complete his set. Those are two of the toughest dates in the series in high grade.
For investors and advanced collectors, this is the actionable takeaway: Do not chase shipwreck or hoard labels blindly. Chase originality. A non-hoard, non-shipwreck 1820 in this condition will outperform a common-date sea salvage coin every time. The market for original Capped Bust halves in AU-58 to MS-63 is exceptionally strong. The supply is fixed. The demand from date-set collectors is relentless.
When you buy a coin like this, you are not just buying silver. You are buying a piece of American history that escaped circulation. It escaped the melting pot. It escaped the ocean. It escaped the cleaning dip. That is rarer than any hoard label.
Conclusion: A Hoard-Caliber Coin Without a Hoard Label
Was this 1820 Capped Bust Half Dollar found in a famous hoard? Based on the provenance, the surfaces, and the dates of the hoards themselves, my answer as a treasure salvor is no — and that is good news. It was not found in the S.S. Central America, where silver would have been destroyed by saltwater. It was not part of the Redfield Hoard, which was a Morgan dollar hoard from a much later era. It was not part of the Saddle Ridge Hoard, which was buried in Nevada in the late 1800s and contained no Capped Bust halves.
Instead, it is something collectors should value even more: a coin that survived through careful cabinet preservation. The thick, golden-gray dirt patina, the flash underneath, the full cartwheel luster, and the full strike for the Overton 103 all point to a coin that never circulated and was never cleaned. It passed through the Chuck Link and Hoosier collections, two cabinets known for quality. Now it anchors Tom’s nearly complete date set.
In my experience, coins like this are the true buried treasure. They do not need a shipwreck to be exciting. They do not need a hoard label to be valuable. Their story is written on their surfaces. And for a collector who understands shipwreck effects, hoard history, and the delicate art of grading Capped Bust halves, that story is unmistakable.
If you are building a set of Capped Bust halves, learn to read a coin’s surface the way I read a wreck site. Look for the luster. Respect the dirt. Never underestimate the power of originality. The finest known examples of certain coins did spend centuries underwater or buried in bank vaults. But some of the finest of all spent them in a collector’s cabinet, waiting for the right person to recognize them. Tom recognized this one. And now, so have we.
